We still use that heavy-gauge tracing paper-type stuff with "Property of London County Council" on every sheet (nicked a lifetime's supply from the school stockroom in '72). Failing that, there's always sliding down a grassy slope (don't use the same place more often than once a fortnight though - even I'm not that 'ard). Wassup with you soft lot with your namby-pamby "absorbent" muck"!
